I was unhappy with my original dealership so I switched to a new one that had a lot of positive feedback, my 55,000 service was a positive experience, except my car still stutters sometimes when I hit the gas, just like it did before. I just got it back 2 days ago. It's not as bad as it was, but it is still doing it. The Audi dealer told me it was caused by a bad coil, which they replaced. I'm just wondering if anyone else has any perspective or thoughts on this. I do like this dealer a lot more than the one I used before, just for the record.
Thanks for any help!

 

There can be numerous possible issues, especially if there is no check engine light. What else did the dealer service/replace besides the coil?
If you got 2.7T got to make sure you load it with premium only.
Otherwise got to globally check all the systems: spark plugs, fuel filter/pressure, alternator output voltage stability, etc...
If all turn out okay got to hook up the engine to global motor analyzer to check primary & secondary ignition performance, which as far as I know dealers will not do...
Best of luck...

 

Thanks for the feedback! The dealer checked it out and it was The ignition coil. My 4.2 Runs great now. I appreciate you getting back to me.
Peace
